Hi there, I'm considering a Yamaha, but have noticed several other 'generic' generator brands for around a third of the price and offer similar specs. What's driving the price difference?
Great question Craig, thank you! Some lesser known brands have their place, really only for people who will use their generator infrequently - in which case you can save some money. Then there are also many cheap brands out there that are a good chance to break down on your first starting attempt!
With Yamaha, firstly - their specs are superior; not only are they the quietest and lightest inverter generators in the market, they are also built to handle more intensive, frequent operation. So with a Yamaha, you know it is going to handle your power demands easily and you can use your unit for multiple applications if required; recreation, home power backup, small business, events etc. It is the premium inverter generator brand in the market.
Secondly, with a Yamaha you get a 4-year warranty (which is much longer than the cheap brands) and you get the support of over 200 accredited service agents around the country. Our experience is that the Yamaha after sales support, servicing and parts support is excellent. You don't get a national service network with the cheap brands.
Hope that help explains the price difference, cheers, Steve!

My product manual for my inverter generator mentions an 'earthing wire / earthing stake' - do I need this?
Hi there, good question. This is mentioned in generator manuals and is a safety feature that will earth the generator. You do have the option to fit an 'earth wire'. Connecting an earth wire and stake is an option available to customer's that purchase a generator.
An earth wire and stake are not supplied with generators that we sell and is application specific. In practice, we do not see customer's do this, especially for inverter generators. It can be something that is implemented for more specialized generators on mining work sites for example...for common applications, it is not common practice to 'earth' the generator with a wire and stake. If you are in doubt, and you have a specialized generator requirement that may need 'earthing', please consult an electrician. Hope that helps.

Is there a way to shut off the petrol supply so I can run the carburetor dry?
Yes, all the Yamaha generators have a fuel valve shutoff (petcock) allowing you to switch off the fuel whilst the generator is operating so the remaining fuel in the carburetor runs dry.
This feature is especially popular if you intend to store your generator in a car, as the petrol fumes ill not permeate through the vehicle thanks to the shutoff valve.

Good morning, Karen here from Semaphore Caravan Pk Adelaide SA. We are getting ready for our trip around Australia. We would like to know what size Yamaha Generator would best suit us? We have solar panel set up, duel battery among other things.
Hi Karen, to be sure you get the right generator for your Caravan trip, its best to know in a bit more detail exactly what you intend to be running. If you just want the generator as backup option to charge your batteries and a few other small appliances then the most popular generator models are the Yamaha EF1000iS and the Yamaha EF2000iS.
However, if you also want a generator to run appliances with a larger draw such as a Caravan air-conditioner, a microwave, a washing machine, a standard kettle etc. etc. then you may need a larger generator such as the Yamaha EF2200iS, the Yamaha EF2400iS, the Yamaha EF2800i or the Yamaha EF3000iSE. In this instance you would need to know the exact starting and running wattages of these larger appliances to ensure you get the right sized generator for the particular make/model of appliances you have. The starting wattage of these appliances is the most important number to obtain. You can do this by checking the product manual or contacting the manufacturer of the appliance (we find this is the safest/most effective approach).
I hope that helps - if you still need help, please feel free to give us a call on 1300 400 122! Thanks.

I plan to leave the generator outside my long term camp setup, what's your best inverter generator that can handle all weather conditions, especially heavy rain?
Hi there, sounds like a nice set up! The short answer is that electricity and water don’t mix. Whilst we are aware that some people run their inverter gensets in all weather conditions, it is not recommended as safe or best practice for your equipment, as inverter generators do not come with weatherproof outlets as standard.
Ideally, you would somehow shelter your generator from the rain. But just remember that fully enclosing your generator whilst its running is not an option - generators need fresh air intake for the engine to run and they emit carbon dioxide, so they should never be contained. Overall, some rain protection but also room for fresh air intake and fume emission is what you need.

How frequently do I have to change the motor oil? Product info says to change it after the first 20hrs, and after this first change?
Hi, after the first oil change, the recommended oil change time frame is every 6 months or 100 hours of use. When in doubt always consult our user manual for recommended maintenance. Thanks!
-
Is the warranty on this product a factory warranty from Yamaha?Â
Yes, you get the full manufacturer’s warranty from Yamaha Australia which would be covered by any local Yamaha service center that works on generators.

Thank you for your very informative website. I am about to have a Duoetto 12V/240V water heater installed in my yacht. It will be run from batteries but I would like the option of using it with 240V from a portable generator. Would this Yamaha 1000w suit?
Hi, great question - we are somewhat familiar with that style of water heater...whilst the Yamaha 1000w generator may be fine, often the information in the product manual is not enough and if possible we'd encourage you to contact the manufacturer (Duoetto) or the distributor and ask for clarification on the peak wattage draw of your particular model. Again, there are many 12V/240V water heater models that can be run easily with a 1000w generator, but its always advised to check with the manufacturer about the peak draw of your particular model to make sure you get the right sized generator...you dont want to buy a generator that isnt big enough to do the job you want.
Thanks, and good luck :)

Considering buying a Yamaha Ef1000is from you. Do you ship to Tasmania? And is the product insured during shipment? Thanks.
Yes, we certainly do ship to Tasmania, simply add your postcode to the freight calculator on the product page to get a shipping price to your location. And yes again; the shipping price includes freight insurance. Many thanks!

Please clarify if the DC charger facility can be used at the same time as the 240AC is being used? The manual is a little confusing regarding this.
Hi - yes, simultaneous use of the AC and DC power is possible, but wattage should not exceed the rated output.
It should also be noted that the DC charge from the generator is not regulated and is mostly designed for 'just in case' situations, i.e. your flat car battery needs a short trickle charge. For full charging of your batteries, you should always use a quality battery charger which connects between the AC output on the generator and your batteries - this will ensure safe and efficient charging of your batteries.
Thanks.

Can I charge my battery pack from the generator?
Hi Adam, and thanks for your question; in short, yes you can. The Yamaha EF2200iS, EF2000iS and EF1000iS units come with DC outlets and 12V charging cables and are popular models to charge battery packs. However, it is strongly recommended that you use a battery charger to charge your battery pack - the DC charge from the generator is not regulated, and so it is much safer and effective to connect a battery charger to your generator, and then the charger to your battery pack to charge up.
The charging cables can be used directly to provide a small trickle for a short period of time in situations such as needing to start a car battery...but once again, for charging your battery packs, ensure you connect a suitable battery charger between the generator and your batteries.

What is an "inverter" generator?
Hi Alison, and thanks for your question. An inverter is a lightweight microprocessor that converts power from direct current (DC) into alternating current (AC). They are a fairly recent advancement in technology from the older style conventional generators. What it means is that the inverter generators produce very clean power which is required to run sensitive electronic equipment such as laptops, mobile phones, camera equipment etc.
The other benefits of inverter generators are that they are typically much smaller and lighter than standard open frame style generators and tend to operate at very low noise levels (less than 60 decibels). Lastly, they are also very efficient; their engine speed automatically adjusts in accordance with the required load, maximising fuel efficiency.
Overall, they are an extremely popular portable power source for camping, caravanning, DIY tasks, small business uses and home power back up. Inverter generators range from around 1000 watts up to 7000 watts. -

Do you guys have some general tips for generator maintenance? Ta
Hi there - good question, yes, we do! Firstly, as a safety note, always stop the engine and let the generator cool down before starting any maintenance work. The five main general tips are;
1. Replace engine oil
2. Check spark plug, replace if necessary
3. Check fuel level and ensure it is fresh fuel (fuel left for a long time can go "off")
4. Check air filter, replace if necessary
5. Clean muffler cover and check spark arrestorYou can also check out this helpful video on generator maintenance tips.
For further maintenance help, you should take your generator to a small engine specialist or an accredited generator service technician.

Hi,Do you know if this will run a sterling pro charge ultra 50a AC battery charger at full? Does the unit's output drop off on a hot 35-40 degree C day?
Hi There,
Without knowing the input power requirements of the charger we are unable to guarantee it will run on this generator, sorry.
The generator will de-rate when the temperatures are high. This is normal for all generators.

I am buying a Yamaha Inverter Generator from you. If I plan to not run it for a period of 4-5 months, so should I just use a fuel stabilizer?
Yes, a good fuel stabiliser will keep your fuel fresh during periods when you are not using your generator and in your case this should be fine.
Other good practice recommendations are:
- Drain the excess fuel in the carburettor after use. All Yamaha generators have a fuel shut off valve (petcock) that you can switch off while the generator is running to use the residual fuel and ensure it does not sit in the carburettor
- Start up your generator every few months for a short period to lubricate internal parts of the unit and even apply a small load to the generator ensure everything is in working order for when you need it next.
Customer Reviews
Great Service and Product Review by Simon CallowThe little Yamaha Generator is an excellent product. Quiet, well made and high quality. Perfect for grey nomad camping trips.(Posted on 1 April 2019)
Fabulous Review by Di ChapmanWe considered putting an auxillery battery in the back of our wagon as we had done with previous vechiles. As we have a solar, 12 volt van we decided to get a generator as if we need to top up batteries in van we would get better value. Also we could use it for minor repairs running powered tools. Easy to start and quiet.(Posted on 23 February 2019)
